JP4 JP1
I like the picco pipes as they're made specify for P7R and in theory to get the best performance.. i read every post of pipe but its difficult a consensus
This dyno result of 9886 pipe surprise me
The JP4 seems to be based on 2046 picco, is that right?
any help will be appreciated
086 rocks....JP-1, JP-2 seriously reduce power output...JP-3 and 4 will work "Okay" .........Picco 2047 and 069 also greatly reduce power output.............. Best pipe is definitely 086 on short manifold..also TTR 2035 works well on short manifold......

Not sure 100%, but the Ofna 086 is very close to 9886 shape wise. The Dynamite 086 appears to have a slightly skinner tube section than the Ofna. It does look the same, but appears to be skinnier to me. I checked these yesterday.

Can anyone tell me if the P7 piston/rod/sleeve is the same as the Trinity .21??
It has probably been asked before but I can't be bothered looking back to find out

yes the Trinity 21, Jammin 21 and Picco 21 are all 100 5 identical......... Marketing machines will tellpeople the timings and stuff are different, but in truth they are all 100 % identical...The Jammin JPX 21 has the same crank as the Picco P7R...

Default p7r evo 2

I just bought this engine today, and the piston & sleeve it very tight. when I start to turn the flywheel with my hand it kinda scrubs a little. I put afterrun in before I tried to turn it. Is this a good thing or what? And will this engine be enough for the jammin crt?

Must be new to nitro engines. Every nitro engine is like this. Thats why you have to heat it up and break it in.

WOW!! That info really rocked my boat!! I'm running a Ofna 053 now (it works ok) , but I was considering getting a JP3 or JP4.

What do you mean when you say some pipes reduce power output??

For example: 086 supposedly gives good power at high revs, so you get a better peak speed, but it isn't as good giving torque in the low rev range...each pipe is good for a determined kind of track / driving style....

Please give us a link to dyno tests, so we can get the best pipe for our needs!!

What do you guys do to get the normal non-picco header to fit on the engine? I hate the way the pipe sticks up in the air when you put the header on. This is why I went with the 069 pipe and header. I want to try other pipes, but need to know what others do.

Thanks,
Tim

You try the Axe Rossi LSK headers. They have the Picco angled slope exhaust port also.
